Flashcache, Bcache, or other write-through solution?

Following some initial research, SSD caching by way of bcache, flashcache, dm-cache or the like, does seem to be a decent solution in terms of performance. However, the current solutions would add additional complexities to the storage layers and Btrfs may eventually add similar features. See here.

From this understanding, I am continuing to focus my efforts into learning Btrfs as fully as feasible, and not worrying about these other options for now. -- AdamT (Talk) 23:43, 21 November 2013 (UTC)
